To all whom it may concern.

Be it known that. 1, Barron L. MARpNEss, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and'useful Improvements in Foldin Boxes, of which the following is a speci cation.

My invention relates to a folding paper box and the object thereof is to produce a simple and eflicient box characterized more particularly by the provision of flaps for locking and strengthening the ends of the box.

In the drawing Figure 1 is a plan View of oneend of a blank cut and scored to form the box Fig. 2 a perspective of the box; Fig. 3 a sectional elevation on the line 3-3 of Fig. 2 but showing the outermost flap in verticalposition and Fig. 4 a plan view of the parts shown in Fig. 3; Fig. 5 a detail section showing a modified form of construction.

Referring to the particular embodiment of my invention as herein shown it will be understood that my invention may be incorporated into either or both the body of the box or box proper and the lid therefor. In the present instance the structure shown may be considered either the body or the lid so that if two similar structures be employed telescoping into each other,a complete box would result.

In Fig. 1 I have shown one end of the blank, it being understood that both ends are similarly cut and scored. This blank is cut and scored as to its body portion to form the bottom 1 and two similar opposite side walls 2. The blank is also provided with the corner flaps 3-3 hinged to the ends of the side walls 2, a main end Wall 4, an irregular-shaped flap 5 hinged thereto on the score line 4 and two narrow flaps 6 between the flaps 33 and 4-5. The flaps 6 have oblique score lines 6 so that their outer portions may be turned inwardly toward each other as hereinafter explained. The outer corners of the flap 5 are extended outwardly to form the tongues 5, the same being cut from what otherwise would be the outer ends of the flap 6. In practice the two flaps 6 are first turned upwardly and inwardly so as to be at right angles to the bottom 1 of the box. The two flaps 3 are then raised and brought inwardly against the then vertical flaps 6, the two flaps 3 overlapping. The

. strengthened by the several plies or thicknesses of the paper or board. After the tongues 5 have been tucked behind the inner portions of the flaps 6 the extension flap 5 is held securely in place, it being impossible for the same to swing inwardly with respect to the box on account of the lower portion of the flaps 6 nor to move directly upwardly because of the engagement of these tongues with the inwardly-folded outeror free ends of said flaps 6 Both ends of the box are constructed exactly alike and the description of the operation therefore applies to both ends.

If desired the flap sections 6 may be foldedin a direction reverse of that herein shown, in which event the extension flap 5 could be made shorter inasmuch as the tongues 5 would interlock with the flap section 6 at a point higher up on the box end. This construction is clearly shown in Fig. 5. It will be understood that when the flap sections 6" are thus reversely turned the tongues 5 can be tucked in openings presented to them at the folded over portions of said flap sections.

1 claim:

1. A folding box comprising a bottom, side walls hinged thereto and opposite ends, each end consisting of infolded corner flaps hinged to the ends of the side walls and adapted to be infolded toward each other, a middle flap hinged to the bottom, a pair of flaps between said middle flap and said corner flaps, and an extension flap hinged to the middle flap and adapted to be locked to the inner side of the box.

2. A folding box comprising a bottom, side walls hinged thereto and opposite ends, each end consisting of infolded corner flaps hinged to the ends of the side walls and adapted to be infolded toward each other. a middle flap hinged to the bottom, a pair of flaps between said middle flap and said corner flaps, and an extension flap hinged to the middle flap and having tongues 5 adapted to be tucked behind the said pair of flaps.

10 ing toward each other, and an extension flap hinged to the middle flap and having corner tongues adapted to be tucked behind the said pair of flaps and the outer ends of said last-named'flaps being located behind said extension flap.
